All right, so our expression here is the fourth root of a squared b times the cube root of a squared b minus the fifth root of a squared b squared.
00:26
So i'm going to do this problem a little differently than i've done some of the others, and i'm going to keep this as a squared b raised to the one -fourth, because there are different ways.
00:37
We hopefully know that by now to do problems.
00:40
This is going to be a -squared.
00:42
B to the one third minus and this is going to be a squared b squared to the one fifth.
00:52
Now if i want to be able to multiply these things together, i need them to have the same denominator.
00:58
And for three, four, and five, that's going to be 60.
01:05
And so this is a squared b raised to the 1560th times a squared b raised to the 1560th times a squared b raised to the 2060th minus a squared b squared raised to the 1260ths now let's go ahead and do all of our multiplication so this is going to be a to the 30th 60th 60th b to the 1560th a to the 4060th b to the 2060th minus a to the 24 60th, b to the 2460ths.

Alright, so now we can do our distribution...
